rnrm scnurrz AND RUEBEN kun'rz, or JUNEAU, WISCONSIN HIGHWAY Application filed April 26,

This invention relates to an improved highway marker, that is, a structure which is especially fashioned and constructed for marking lines on the surface of a highway such as are employed at thepresent time for guiding traffic on the highway.

It is a matter of common knowledge that at the present time, white paint lines are employed in various ways on public highways for aiding in separating and guiding motor vehicle trafiic and the like. The purpose of the present invention is to provide a practical: device for accomplishing this result in an expeditious and economical manner, said device being constructed to permit it to be attached to a truck body in such a position as to permit the painted line to be formed accurately, distinctly and rapidly.

Briefly stated, the improved structure for accomplishing this result is characterized by a frame provided with a plurality of Wheels arranged in two pairs and there being an endless belt trained over each pair of wheels and said belt being so constructed as to function as marginal retainers for the paint line whereby to regulate the width thereof and to facilitate the making of the line from a rap idly flowing stream of paint received from an appropriate receptacle on the carrying truck.

The particular structural details and their relative arrangement and association Will become more readily apparent from the fol-,

lowing description and drawings. In the drawings: r

Flgure 1 1s a side elevation of a marker constructed in accordance with the present invention.

Figure 2 is a transverse section on the line 2-2 of Figure 1.

Figure 3 is a diagrammatic small elevational view showing the manner in Which the marker is attached to a truck body.

Figure 4 is a top plan view of the structure seen in Figure 3.

In Figures 3 and 4, the marker is generally designated by the numeral 5. The body of the truck is represented at 6, and'one of the truck wheels at 7 As detailed in Figure 1, the markercom- MARKER 1930. Serial No. 447,653.

prises a substantially rectangular frame in cluding a pair of spaced parallel side rails 8 having end members 9 and 10 connected thereto. The numerals 11 and 12 designate standards including adjusting sleeves 18 and 1a respectively. These sleeves are connected at their upper ends to angle braces and at taching bars 15 which fasten to the body 0 v the truck as represented in Figure l.

The numeral 16 designates a horizontal brace which is connected with the sleeves 13 and 14 andwhich includes an end portion 17 which is also connected With the truck body. This permits the device tocbe adjusted and to be self-levelling. V

The standards 12 fit telescopically inthe sleeves and permit the frame to raise up and down according to the irregularities of the surface. This adjustable mounting of the frame is a desirable feature. H The numeral 18 designates a cross bar having a bracket 19 attached thereto and the bracket 19'serves to secure the paint feed pipe 1 20 in place. This feed pipe terminates at its lower end in an apertured distributing nozzle 'or head 21 located in a surrounding shield and guard22 which as seen in Figure 2 is of such shape and proportion as to dispose the discharge mouth in close proximity to the road surface 23 for distributing the paint evenly and uniformly. b p

7 The parts 20 and 21 form a paint spray and the shield restricts the spread or delivery of the paint on the road surface. ,There are two pairs of grooved rollers mounted for rotation on the frame structure. The rear rollers are, designated by the numerals 24, the front rolls ersby the numerals 25. Endless belts 26 are trained over these rollers. The belts are of V-shaped cross sectional form and the apex portion of the belt fits into the grooved periphery of the wheel. 4,

The front: wheels are adjustably' mounted through the medium of the belt tightening rods 26. The belts run alongside of the dis-' charge mouth of the guard to limit the spread of the paint in a transverse direction. Thus 7 the spray devicetoget-her with the guard and. the endless belts restricts the marked line onv the highway surface.

The gist of the invention, it will be understood, is in the provision of an automatically adjustable or self-levelling frame which is susceptible of being attached to a truck body, whereby to permit the truck to carry the frame along the highway for marking purposes.

The frame is provided with paint spraying and speading means and the line of paint is marked along the perimeter edges through the medium of the endless belt trained over the front and rear pairs of rollers carried by the frame, said belt being maintained in frictional contact with the highway surface by the weight of the frame itself.

The paint delivery pipe and nozzle is relatively fixed with respect to the truck body and the guard is vertically movable with respect to the distributing head, thus forming a unique arrangement and cooperation of mechanical details fulfilling the requirements of a marker of this class in a highly practical and satisfactory manner.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice if desired.

We claim:

1. In a structure of the class described, a frame, a tapered depending shield rigidly mounted between the side bars of the frame and embodying a relatively narrow discharge mouth located in close proximity to the highway surface, a paint delivery pipe, a distributing apertured head carried by the discharge end of the pipe and confined within said shield, and edge confining means on said frame associated with the discharge "end of the shield and including two pairs of-grooved rollers provided with a belt mounted in the grooves, said belt being of endless form and serving to prevent the flowing paint from spreading beyond predetermined limits, whereby to restrict the width of the mark on the highway surface.

2. In a paint marking device of the class described, in combination, a wheel-supported truck body, a pair of depending vertical sleeves, means rigidly attaching said sleeves to the body, bracing means for the sleeves, a horizontal rectangular frame disposed below the plane of the body and including spaced parallel side rails, a pair of upstanding standards connected with the end members of the frame and fitting telescopically in said sleeve to permit the frame to be substantially selflevelling and to move toward and "fromthe truck body, pairs of front'and rear grooved rollers mounted for rotation on the side bars of the frame, endless belts fitted in the grooved peripheral portion of the rollers, a shield mounted between the belts and frame bars, a paint delivery pipe fastened to said frame, a. distributing head on the discharge end of the pipe, said head being confined within said shield.

3. In a highway marker of the class described, in combination, a portable carrier, a pair of depending vertical sleeves rigidly mounted on said carrier, a substantially horizontal marker frame, a pair of standards mounted on and rising from said frame and fitted telescopically in said sleeves to permit free vertical reciprocation of the standards in the sleeves and to render said frame substantially selflevelling to accommodate irregularities in the surface of the highway, paint distributing and marking means on said frame embodying a spray nozzle, an anti-splash shield embracing said nozzle, and edge-defining means for limitingthelongitudinal edges of the painted mark, said edge defining means comprising a pair of front and rear grooved rollers carried by said frame, a pair of endless V-shaped belts trained over said rollers, and tightening means for the belt.

In testimony whereof we afitix our signatures.
